angularjs-structure-styleguide
==============================
Basic, personal, opinionated style on structuring your AngularJS, adhering to [John Papa](https://github.com/johnpapa)'s [LIFT principle](https://github.com/johnpapa/angularjs-styleguide#application-structure-lift-principle).
**What is LIFT?**
- ```L```ocating our code is easy
- ```I```dentify code at a glance
- ```F```lat structure as long as we can
- ```T```ry to stay DRY (Don’t Repeat Yourself) or T-DRY
## Unmaintained
This style guide is no longer maintained.

## 1. Context
This was created to offer a *more* in-depth guide for AngularJS developers that want their apps to scale, maintainable, and whatever
**This guide gives emphasis to components or directives** inspired by [ReactJS](facebook.github.io/react/) and [Flux](facebook.github.io/flux/). For more information in regards to this emphasis, check this [article](https://medium.com/@srph/breaking-down-angularjs-to-smaller-components-f2ab70a104d0) I wrote on Medium.
Please, feel free to diverge from this guide.

## 3. App
The ```app``` folder contains all the app's states. And each state may contain the controllers, directives, services to be **specifically** used for itself or child states.
```
├── app/
| ├── user/
| | ├── i18n/
| | | ├── en.js
| | | ├── kr.js
| | ├── components/
| | ├── tests/
| | ├── partials/
| | ├── user.state.js
| | ├── user.controller.js
| | ├── user.html
├── ...
```
### Q: What is a state? ###
Used to register a state, see [ui-router](https://github.com/angular-ui/ui-router). This also has been asked before, see [this issue](https://github.com/srph/angularjs-structure-styleguide/issues/1).
### Q: What if I started having more than 1 partial, controllers, and other things?
**Stop using multiple controllers, partials, services**. It is more **recommended** to use directives for the sake of modularity and maintainability. It is only okay to use partials for chunk of non-functioning mark-up.
```
├── app/
| ├── user-profile/
| | ├── components/
| | | ├── Avatar/
| | | | ├── Uploader.js
| | | | ├── Webcam/
| | | | | ├── Webcam.js
| | | | | ├── WebcamShootButton.js/
| | ├── user.state.js
| | ├── user.controller.js
| | ├── user.html
├── ...
```
### Q: What if I have nested states?
**As much as possible, try to avoid nested *directories* of states. For example, we have this state hierarchy:**
```
- main
- user
- user.create
- user.edit
- user.delete
- profile
- profile.create
- profile.edit
- profile.delete
```
This is how we structure our directory. Why? This way, nested states can be easily found and understood while adhering to the **LIFT** principle.
```
├── app/
| ├── news/
| ├── news.create/
| ├── news-category/
| ├── news-category.edit/
```
### Q: How do I indicate a url nest or a state nest?
**Use ```.```(dot) for states of the same module**. For instance, if we have the ```users``` *CRUD* module, then we'd have ```users.create```, ```users.edit```, **...**).
**Otherwise, use ```-``` to signify hierarchy**. For instance, we have a ```group``` module which is under the ```users``` module, then we'd have: (```users```, ```users.create```, **...**, ```users-groups```, ```users-groups.create```, **..**).
To elaborate, here's an example: an app consists of a news CRUD [url: ```/news/*```] and a news category CRUD [url: ```/news/categories/*```]. We expect it to have these states:
```
news (abstract state)
news.index
news.create
news.edit
news-category (abstract state)
news-category.index
news-category.create
news-category.edit
```
This is how we create our directory:
```
├── app/
| ├── news/
| ├── news.index/
| ├── news.create/
| ├── news.edit/
| ├── news.category/
| ├── news-category.index/
| ├── news-category.create/
| ├── news-category.edit/
```
### Q: What if my state is composed of two words?
**Use ``camelCase``; do not separate it with a ```-```(dash).** Do not use ```-```(dash) to signify that a name consists of two words. Use it to signify a nest or hierarchy. If a state consists of two separate words (e.g, soulja boy, sticky nav), use ```camelCase```. For example, ```souljaBoy```, ```stickyNav```.**.
Why? This allows us to properly signify and understand what a dot (```.```) and dash (```-```) does.
```
├── user/
├── user-awesomeName/
├── user-anotherModule/
├── user-maybeAnotherModule/
├── user-thatModule/
├── user-thatModule.index/
├── user-thatModule.create/
```
### Q: Where do I put my tests or i18n?
**Tests and i18n should be put close to our components or state as possible.**
*Why?* This avoids the replication of our structure for our tests; and, makes them easier to view.
### Q: How do I handle each language for the i18n?
**The filename of each i18n should signify only the language it is supposed to handle**. If a component only has one i18n file, simply put it at the same directory it will be used with.
```
| ├── user
| | ├── en.js
| | ├── user.controller.js
| | ├── user.state.js
| | ├── ...
```

## 4. Core
The ```core``` folder contains all ```modules```, app ```bootstrapper``` (see [```angular.bootstrap```](https://docs.angularjs.org/api/ng/function/angular.bootstrap)), and all *common* or *shared* files (in short, non-specific components) used in the app such as ```services```, ```constants```, ```controllers```, ```resources```, ```utils```, and ```filters```.
```
├── core/
| ├── constants/
| ├── filters/
| ├── resources/
| ├── services/
| ├── utils/
| | ├── progress.config.js/
| | ├── restangular.config.js/
| ├── app.js
| ├── bootstrap.js
| ├── constants.module.js
| ├── components.module.js
| ├── filters.module.js
| ├── resources.module.js
| ├── services.module.js
```
### Q: What does each of the js file in the *root* of the ```core``` folder do?
- ```app.js``` is our application module, the highest-level module, which contains all other modules. For instance, ```angular.module('app', ['app.resources', 'app.directives', 'app.services', 'app.constants']); ```.
- ```bootstrap.js``` does nothing but bootstrap the app ```angular.bootstrap(document, ['app'])```.
- ```*.module.js``` is the module to be respectively used for each (all *constants* in the ```constants/``` directory should use ```constant.module.js```).
### Q: What are ```resources```?
These come in handy when you frequently request an API for data. Fill in ```resources``` with your $http-service-wrappers to wrap ```$http``` or ```Restangular``` methods, or store data from a server response. Otherwise, put in the ```service``` as a normal service.
## 5. Components
The ```components``` folder contains mostly general-solution|non-feature-specific ```directives```.
```
├── components/
| ├── StickyNavThatDoesThat/
| | ├── tests/
| | ├── StickyNavThatDoesThat.spec.js
| | | ├── Hamburger.spec.js
| | | ├── Search.spec.js
| | ├── i18n/
| | | ├── en.js
| | | ├── jp.js
| | | ├── kr.js
| | ├── tests/
| | ├── StickyNavThatDoesThat.js
| | ├── Hamburger.js
| | ├── Search.js
| ├── AwesomeProgressBar/
| | ├── i18n/
| | ├── tests/
| | ├── AwesomeProgressBar.js
| ├── components.module.js
```
### Q: Why is this named as ```components``` not ```directives```?
It took me a long while to decide whether how it should be named. After some time, I preferred to use ```components``` *because* our ```directives``` are actually being used as components. Again, your preference.
### Q: Why are the directives separated from other angular modules?
I had decided to separate directives because:
1. Directives are way too large to be nested inside the ```core``` folder.
2. They need emphasis and will contain mostly a large part of your app
**Write the file names of your directives (components) in StudlyCase**.
*Why? To emphasize components.* In the future, I might tweak a huge part of the guide to *StudyCase*. *camelCase* does not seem to give proper emphasis to itself, so.

## 6. Overall
Do not forget that this is a personal, opinionated structure styleguide. Although I have been using an almost-similar structure in production, your structure will vary on your project (team size, etc) from time-to-time. Make sure to keep it simple.
It is *always* better to create feature-based instead of role-based structure. Because, based on my experience, role-based structure will always be harder to write, read, and maintain.
Like I said in the [Context](#1-context), please feel free to diverge.
